Vectorlike leptons and inert scalar triplet: Lepton flavor violation, g-2, and collider searches

We investigate simplified models involving an inert scalar triplet and vectorlike leptons that can account for the muon g - 2 anomaly. These simplified scenarios are embedded in a model that features W' and Z' bosons, which are subject to stringent collider bounds. The constraints coming from the muon g - 2 anomaly are put into perspective with collider bounds, as well as bounds coming from lepton flavor violation searches. The region of parameter space that explains the g - 2 anomaly is shown to be within reach of lepton flavor violation probes and future colliders such as HL-LHC and HE-LHC.
